Method For Setting Precious Stones and Ornament Made Thereof

ABSTRACT

This technique includes setting of 13 round cut stones forming a flower shape cluster, by setting the all 13 stones at three different levels. In these 13 stones there are 3 different categories of sizes: bigger, medium, and smaller, the bigger size contains 1 stone, the medium size contains 6 stones and the small size contains 6 stones. In the medium and small size category, the stone size is defined by a specific ratio to size category. This technique of setting cluster has three different height levels in which big, medium and small size stones are set. This entire construction of 6 small, 6 medium and 1 big round stone to create a cluster with complete diamond look, there is no negative gap seen in between the two stone and no metal is visible from the seat. This cluster creates an illusion of one complete flower shape diamond.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Indian Application No. 2794/MUM/2015 which was filed on Jul. 23, 2015 and Indian Application No. ______ which was filed on Feb. 26, 2016 both of which are hereby incorporated by reference in their entirety.

FIELD OF INVENTION

This invention relates to setting of stone in jewellery making. More particularly this invention relates to technique of setting of 13 stones forming a flower shaped cluster by using nick and prong set method.

The drawbacks in the existing or prior arts are as provided below:

-   -   The air-gaps were visible in the centre, around the centre stone         in the prior arts; to fill the gaps there was the need to add         prongs, making the look in the centre metallic.     -   Due to the addition of diamonds, however small, the brilliance         of the stones, because of the setting is enhanced. The diamond         refraction makes the look more diamond intensive as opposed to         its predecessors where the centre was more metallic.     -   This setting is made of 13 stones, that creates a flower where         the prongs being inset into the silhouette of the setting,         making it clean and better defined as a flower and unlike its         ancestors of pressure setting.

The advantages of the instant invention is as provided below:

-   -   Clean look     -   Less metallic     -   More flash     -   More perceived value     -   Pocket friendly, due to the size of the centre stone used     -   The setting is done to create a distinct design that emulates an         illusion of a diamond cut into a flower.     -   It is an evergreen and classic shape that can easily blend in         all designs, all market segments.     -   It breaks away from the round composites we've been seeing for         years and brings in the fresh shape of a flower.

SUMMARY OF THE INVENTION

This invention is a original and unique technique of setting 13 round precious stone with three different sizes, each size has a specific ratio of size to the biggest size in order to create a beautiful looking flower shape cluster, this technique do not allow to form any negative gap between two round stone.

DETAIL DESCRIPTION OF THE INVENTION

In the first step Cluster of any precious metal is made as shown in FIGS. 1 through 6. The mounting is made by casting or machining process of any precious metal, it has three different levels for steps shown as 1, 2, 3, in FIG. 3. Level 3 is at the lowest step and small size stones are set at this level, level 2 is at middle and biggest stone is set at this level, level 1 is at the top and medium size stones are set at his level.

At first step the stone 7, 8, 9, 10, 11, 12 of small size stone of 0.8 mm are set in at level 3 and secured with nick grooves raised from the surface of the metal, as shown in FIGS. 7 through 12.

In second step stone 13 is set at level 2 that is bigger stone 13 of size 2.5 mm. is secured by making grooves from the nick surface of the metal, as shown in FIGS. 13 through 18, and in particular, by cross-sectional view 4 in FIG. 18.

In third step stone 17, 18, 19, 20, 21, 22 is set at level 1 that is medium stone of size 1.8 mm is secured by shared prongs 23, 24, 25, 26, 27, 28 between two stones as shown in FIGS. 19 through 24, and in particular, by cross-sectional view 15 in FIG. 23, which shows small stones 7, 8, 9 sharing prongs with medium stones 18, 19, and 20.

FIGS. 25 through 28 show all the stones set as per the above steps and forming a beautiful flower shape cluster. These flower shape closed can be created with any size of stones in round shape, but the total number of stones must be 13 and must be categorized in three sizes small, medium, large. These sizes always have the ratio in the 1:0.72:0.32.

For above example we have used the stone size of 2.5 mm, 1.8 mm, 0.8 mm for bigger, medium and smaller sizes respectively.

FIG. 29 shows a rear view of the flower-shaped cluster, opposite FIG. 25, to illustrate that the metal of the mounting is pulled over the stone in the nick setting at sides 29 and 30 and the adjacent prong is holding the stone from a third side.

The present invention is not limited to the above-described embodiments, and various alterations, modifications, and/or alternative applications of the invention may be possible, if desired, without departing from the scope and sprit of the invention, which can be read from the entire specification. all these possible alterations, modifications, and/or alternative applications of the invention are also intended to be within technical scope of the present invention.

This technique includes setting of 13 round cut stones forming a flower shape cluster, by setting the all 13 stones at three different levels. In these 13 stones there are 3 different categories of sizes bigger size, medium size, smaller size, the bigger size contains 1 stone, the medium size contains 6 stones and the small size contains 6 stones. In the medium and small size category the stone size is defined by a specific ratio to size of bigger size category.

This technique of setting cluster has three different height levels in which big size, medium size and small size stones are set, the bottom most level has the small stones set on the surface of the wall and fixed with a nick groove engraved from the base metal surface to secure the stone.

The next level that is middle level, this starts little above the small size stone, at this level the bigger size stone is placed above the small size stones so that the girdles of the big size stone are touching the surface of the metal and table is raised above the top of small size stone. This stone is again secured with the nick groove engraved from the base metal surface to secure the stone.

The third and top most level contains the medium size stones. The 6 stone are set at the top most layer of the cluster and set with one prong shared between two stones securely to form prong setting. This entire construction of 6 small, 6 medium and 1 big round stone to create a beautiful looking cluster with complete diamond look, there is no negative gap seen in between the two stone and no metal is visible from the seat. This cluster creates an illusion of one complete flower shape diamond.
